Tacstar carbon fiber handguard - TacStar Carbon Fiber AR-15 Handguard

Bang for the buck. This handguard is a great deal. Nice that it uses a standard barrel nut. You can even use a titanium one if wanted. The carbon fiber is thicker than the other 2 brands I own. One starts with an F and one with a B. The F branded one is nice, but the Tacstar is a better deal. Solid lock-up very rigid. 12" hand gaurd and milspec barrel nut was 9 oz on my postal scale.
